Iron Scrap Recycling
Metal is divided into ferrous and non-ferrous metals. Ferrous metals are called metals that have iron, and metals that do not have iron are called non-ferrous metals, each of which has its uses and characteristics.
non-ferrous metals are aluminum, copper, lead, silver, brass, zinc, and tin, also valuable metals like gold and silver:
Ferrous metals also include valuable metals like steel, stainless steel, cast iron, carbon steel, and wrought iron:
In this topic, we would like to focus on the iron scrap recycling method and its processes:
Iron scrap Recycling, or its process, is such that the first stage is the collection of iron metal. Then, the stage of its processing, and finally, it crushes and melts in furnaces with high temperatures that produce these furnaces, sheets, and blocks. Ultimately, metal product manufacturers buy these sheets and blocks.
Now we want to point out more precisely the method of recycling iron scrap and its processes:
As explained earlier, the first stage of the iron scrap recycling process is the collection process. After that, many products contain ferrous and non-ferrous metals that are collected and ready for the rest of the process.
The next stage of iron scrap recycling is separation or sorting; now, the question is how to separate iron scrap in the recycling process. Sensors perform scrap separation in iron scrap recycling operation that separates the metals used in scrap metal.
The subsequent processing stage is the recycling of iron scraps, in which we crush the metals, and then these crushed metals are guided on conveyor belts to separate the iron scraps from the rest of the parts.
We reach the section on melting iron scraps, which we melt in large furnaces. The melting time of junk in the furnaces is different, which can last from a few minutes to several hours; the size of the furnaces determines the time difference; the larger the size of the Furnace, the less time it takes to melt the iron waste.
We perform purification operations to ensure that the final product from the oven is free of contamination and of good quality. The electrolysis does this operation.
We reach the last stage of iron scrap recycling, which is freezing. After melting, the metals are placed on the conveyor belt to cool, and then they are solidified in various forms, such as sheets, tubes, ingots, bars, etc., which we can easily use in multiple industries.
So, as a result, the purpose of recycling iron scrap is both a financial incentive and to prevent environmental damage because metals contain chemicals such as mercury that can pollute water and soil.
Iron Scrap Yards in the Process Of Recycling
Iron scrap yards in the recycling process can be in different forms depending on the amount of waste. Therefore, there are many options on the table; for example, for those just starting to collect scrap, their scrap yards can be in a corner, underground, garage, etc.
A shed or parking lot can also be a hollow option for iron scrap storage, but generally, how much space depends on people’s needs!
An open place may be a good option at first glance, but keeping scrap in open positions first attracts the attention of thieves, and in many neighborhoods, some laws prevent the storage of such waste.
So, we can conclude that iron scrap recycling, if you want to keep a small amount of scrap, is one good option in the corner of the yard or underground, but if you have a large amount of junk, renting a warehouse is a more suitable option.
After some time, even the warehouse space may not be enough to collect iron scrap; now we want to point out a point that makes the maximum use of the iron scrap warehouse space, the thing that makes the full use of the iron scrap warehouse space And also it becomes easier to manage the scraps to classify the waste.
The scrap can be classified, but it wants to be any metal. At first glance, this may seem like a challenge, but in the future, it will free up more workspace, and as a result, your work will be more productive.
Iron Scrap Processing in Recycling Operations
Iron scrap processing in recycling operations is in such a way that when iron scraps and scraps etc., are stored in the warehouse, a series of processes are carried out on them, which leads to optimal and repeated use.
After the processing of iron waste, the scrap does not lose its quality in any way; This point indicates the repeated processing of iron scrap.
We want to know the difference between iron scrap processing and recycling. Stay with us!
As mentioned earlier, iron scrap recycling is a process that leads to the production of a final product that we use. But we perform the iron scrap processing one step before iron scrap recycling, and practically, iron scrap is pure and ready. And practically, it is pure and ready-to-smelt iron scrap that has been separated and processed.
There are five methods for processing iron scrap that we will consider:
- pressing method
In this method, the press machine compresses and changes the shape of metals. It performs the deformation without cutting or machining.
- The method of shredders or crushing machines
Shredder machines are machines that enter scrap, and after melting the output, they deliver homogeneous and high-quality waste. The positive point of this type of machine is preventing the explosion of capsules that may happen in the previous method. In this way, we will not have.
- Briquetting method from iron shards
The compression of iron shards (pleats) formed Briquettes. Many works related to steel use These briquettes.
- Cutting method using air cutting
One of the methods is that when a company mixes gas and oxygen, a cutting operation is performed, also called air cutting or gas air cutting. This method is used in all kinds of metals and is not only for iron waste!
- scissors method
This process is carried out by mechanical devices, just as scissors cut paper; these devices can also cut iron sheets, whether they want to be thick or thin, and also cut iron profiles. In addition, these devices have different sizes and capabilities that we can use depending on the need.
The Impact of Iron Scrap Recycling on Environmental Protection
Metal scrap recycling significantly impacts the protection of the environment and activities that deal with iron; that’s why experts in this area have always emphasized the effect of recycling these wastes.
Iron scrap consists of recyclable materials from producing and consuming products such as vehicle parts, building materials, and their additional materials.
This scrap, in contrast to waste, has a market value, particularly in recovered metals, and we can recover non-metallic items also. These wastes are found both in commercial areas and in residential environments.
Metal scraps are usually taken to the metal scrap collection site and then to the factory to melt and produce new products.
Depending on its location, this environment may allow customers to view large amounts of iron and purchase items if needed before sending scrap metal to smelters.
Although usually, many of these scrap collection environments with large amounts of scrap metal do not.
The Benefits Of The Recycling Process
As mentioned, after collecting and transferring the scrap to warehouses, the recycling companies start recycling the waste, which we have comprehensively reviewed in the iron scrap recycling section.
If we want to mention the benefits of iron recycling, the most crucial discussion is that it prevents the production of dangerous greenhouse gases that can prevent water, soil, and air pollution.
In the industrial sector, iron scrap recycling has many advantages, which include:
- Save energy up to 70%
- Saving raw materials up to 90%
- Significant reduction in air pollution
- Save water consumption and reduce pollution of water sources
- Significant savings in the use of iron in the production of each ton of steel
Also, by doing the recycling process, we can prevent mining significantly, and the products obtained from the recycling process are of high quality and can be considered factory products.
